Phosphoryl Azides as Versatile New Reaction Partners in the Cu-Catalyzed Three-Component Couplings
摘要:
[GRAPHICS]Phosphoryl azide was successfully employed as an efficient reacting partner in the Cu-catalyzed three-component reaction with 1-alkynes and amines to produce the corresponding phosphoryl amidines in high yields. A range of fruitful applicability of the produced amidines was also demonstrated such as an alkoxide exchange and asymmetric alpha-alkylation of optically active BINOL-derived amidines.
